To all whom 'it 'may com-em:

Be it known that I, EINAR .MORTERUD, a subject of the King of Norway, resicling at Torderd, near Mess, in=the Kingdom of Norway, haveinvented certain' new and useful Improvements in -Apparatu-s-for Transtion F.- The fluid to be heated passes'in at G, entel-s the bent tubes and passes out at mittin Heat from' one Medium to Another; and I %o hereby declare the following to be agfull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the a& companying drawings, and to letters or` figures of reference marked thereo1 i,' which' form a, part of this specification. i My invention relates to` apparatusfor transmitting heat from. one medium to *another, as for instance, steam-boilers,'c'ondensers, feed water heaters., heaters used with cellulose dgestersand the like.

My' invention relates more especially to that class of heaters in wh rfeh fireely expanding tubes constitute the through which the heat istransmitted." v a Exanples of such apparatusare shown in the accompanying drawingg in which- Figure 1 is a lngitudinalsection through a heater particularly adapted for use in cel-' lulose factories;` Fig. 2 is a cross section of the same, and Fig. 3 is a longitudinal sec;

tion of a steam boi1er'.'

. In Figs. l and '2 the heater is composed ofthree castings, A, B and together, and a plurality' E Secured in a plate D held between the casting-s A and B. The casting A has a parti- C, suitably bolted The heating medium passes n at I in the casting B, rises within the latter and'psses out at K.

In a heating apparatus of this and similar' i kinds the coeflicient of heat transmission is dependent on the velocity with which the.

heating'medium circulates; the greater the velocitfy the greater 'the coeflicient of transmission.. Great velocity of the heating media is also advantageous for other reasons,

us for nstance, to prevent or diminish the formation of deposts ofsoot, boiler ,scule and the like on the surfaces `of the heating Bpecflcati of Letters Patar-it. j A l ca ion mea mb mos. Serial No. &20,462;
